Re: Update Firmware on M4 SSD on Macbook Pro without optical disc?

Hi Marcosi,

The SSD firmware version is stored on the SSD itself so the upgrade does not need to be carried out on the system the SSD will be used in. The easiest way to upgrade the firmware is by connecting the SSD to a system that has a CD drive.

If this is not possible, you can follow these steps to create a bootable USB flash drive and upgrade the firmware from that.

1. Connect an empty USB flash drive

2. Download rEFIt-syslinux from the link below. This will allow your USB drive to be recognised as a startup volume by the mac.

This doesn't work on my MacBook Pro (2.4 GHz i7) with OSX 10.7.4 and it is well documented here on the forums that this will not work with all Mac's. We need a solution to this problem for those people who purchased an M4 and do not have an optical drive.

Try to create the boot disk on a Windows PC with Rufus ( http://rufus.akeo.ie/ ). Some utilities do not make the boot disk properly... Download the bootable ISO file from the support website. In Rufus, select "Create a bootable disk using ISO Image", click the disk icon on the right and find the ISO file you downloaded... I also had the problem "No bootable device found" earlier on a Windows laptop when trying to boot off a USB drive using some other ISO-USB burn tool.. Alternatively, you can try to restore the ISO file to a USB stick using Disk Utility... Not sure if it would accept a Linux disk image though...
